1 Claim.

This invention relates to an apparatus for the exercise of the abdomen.

The main features of the invention are a flexible clapper and a guidepiece for the head of said clapper within the apparatus, said clapperspringing off the guide piece and ringing a bell intermittently when theabdomen compresses the apparatus during the performance of abdominal(diaphragmal) breathing exercises.

It is an object of the present invention to provide an apparatusallowing proper regulation of breathing exercises and practice of normaland regular breathing;

A further object is the correction of irregularities of breathing;

And still another object of the invention is an apparatus facilitatingexercises strengthening the abdomen by its regular expansion andcontraction, and thereby improving the circulation of blood.

The accompanying drawing shows an embodiment of this invention.

Fig. 1 shows a side elevation of the apparatus, and

Fig. 2 shows a plan view of the apparatus, a part being out 01f in orderto show the inside of the apparatus.

The apparatus consists of a frame which is curved in such a way as toleave appropriate space between the outer plate I and the inner plate 2of the frame. On the inside of the outer plate there is provided a bellbody 3 and a guiding leaf spring 4. On the inner plate 2 there isprovided a clapper consisting of a leaf spring stem 5 and a head 6.

The apparatus, is fastened to the lower part of the abdomen by a belt orsimilar device. When breathing exercises are performed the outer and ofabdominal pressure the inner plate 2 is curved again, the guiding spring4 again engages the clapper head 6, until the latter is released asabove-described. This enables the user to perceive easily the tact ofhis breathing, and causes him to repeat his breathing exercises properlyregulated. The object of using this apparatus is thus to strengthen thepressure in the abdomen, to make the circulation of blood vigorous and,consequently, to improve the general health of the body, by giving theabdomen normal and regular movements of expansion and contraction.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, 1 declarethat what I claim is:

An abdominal exerciser, comprising a flexible, elastic frame ofpredetermined length and adapted to be attached to the body of the user,said frame being curved so as to leave a space between the outer and theinner part of said frame, a bell within the outer side of said frame, aflexible clapper on the inner part of said frame, said clapper and saidinner part of said frame being directly actuated by the movements of thediaphragm of the user and a guiding spring within the outer part of saidframe for the alternate retention and release of said clapper.
